Table of thresholds against which the agent should check for exceptions.

This table describes conditions for setting and resetting alarms.

Alarms may be set on absolute values - i.e. the current integer value of the sampled variable - or on delta values - i.e. the difference between the current or last value.

Alarms may be GreaterThan exception alarms, LessThan exception alarms, EqualsTo alarms etc. See svrThrAlarmType for differences.

Hysteresis is introduced by providing thresholds both for setting and resetting of the alarm state, thereby limiting the number of traps that will be sent on alarm triggering.

Alarms may be created to persist across agent reboots, but this is not recommended for dynamic table variables.

The triggering of an alarm will change a state variable in the conceptual row. It may also trigger the sending of a trap, the local logging of an event, or the triggering of a locally- defined action.
